Cross-country comparison over absolute dates⮸
Cross-country comparison with approximately aligned start days⮸
Per-country analysis with exponential and sigmoidal projections, and new cases analysis⮸
IMPORTANT: The projections are only accurate if the fit is good (it often isn't), and assuming nothing changes
going forward. The sigmoid is omitted if a reasonable fit can't be computed, but this still doesn't mean that
the fit is good if it is shown.
The dashed lines show best fit projections from a few previous days for comparison.
